To all whom it may concern:

Be it known that I, STALEY D. POOLE, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in WheeledCultivators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This inventionrelates to cultivatorsfand more particularly to that classof machines in which gangs of plows or cultivating de vices areconnected with a wheeled support- ,in frame and known in the art as awheeled cu tivator. V v

The main object of the invention is to provide air improved double'rowcultivator having three pivoted supporting and guidiirg 'wheelsconnected and adapted to operate in unison for steering purposes,together with foot-levers or trcadles for operthe machine is movingstraight ahead; also a pivoted tongue having a limited longitudinal andsidewise swinging movement adaptf ing it to aid in steering, the frontwheel spindle pivotal point about which the tongue may swing; also meansfor connecting the rig-- shifting levers with the steering mechanism soas to enable the operator to turn the three steering wheels in unisonand at the same time shift the cultivator gangs or rigs laterally in oneoperation.

The invention will first be hereinafter more particularly described,with reference to the accompanying drawings, which are to be taken asapart of this specification, and then pointed out and defined in theclaims at the end of the description.

Referring to said drawings, in which aha same reference letters are usedto denote corresponding parts in different views the ing mechanism to bepresently described. As shown the axles of the side wheels B, B, areeach rigid with an upright spindle or standard which is fitted in atubular bracket bearing 1) attached to the rear cross bar a of themachine frame, which cross-bar together with said tubular brackets formthe arched axle beneath which the gangs of cultivating devices arearranged and connected with the supporting frame in such manner as to.adapt them to be raised and lowered steering wheel B is fitted, thusforming a substantially triangular frame, to which the cultivators maybe connected. Intermediate braces a preferably of channel iron, mayextend from a point about midway of the rear arched axle cross-bar tothe lower end of th bracket-bearing E, and the members a, a", aresecured to said bracket-bearing E, one above and the other below thetongue or pole F, by bolts entering apertured lugs or ears e, e, whichproject from the bracket.-

bearing in opposite directions, as shown more clearly in Fig. 7 of thedrawings. The cross-bar and evener D is connected with the arched axleby a draft-rod G, at each side, preferably having a hook at one endengaging an eye on asocket g, fitted on the standard or upright spindleof the side wheel B, and a hook at the other end engaging a loop orclevis g secured to the cross-bar and evener D. r

The cultivator gangs are pivotally connected at their forward ends tothe laterally projecting arms of a bail H, one at each side ,of themachine, carried by a sliding trolley-frame I, which is mounted on therear cross-bar a, and also to depending hangers K, which have a pivotalconnection at their upper ends with the frame-bar and evener D, to adaptthem to swing toward either side; to permit the gangs to move laterally.Underneath and parallel with the frame-bar and evener D may be secured abrace d, by means of diagonal braces d, at

each side of the center, and vertical braces 1d at the center, therebyforming. a. very strong and durable yet simple and inexpensive frameconstruction, which will serve also as an evener. The lower bar or braced may be bent downward centrally to provide a space between the two barssuflicient to permit a limited vertical movement of the rear end of thetongue F, which is confined between said bars D and (Z and said braces(1 The intermediate frame bars a may aiso be bolted to said braces (1Each of the vertical arms or spindlesof ed as follows: To a cross-barconnecting the 7 frame bars a, at a convenient point pivoted arocking-lever L, having an upstanding arm 1 pivoted to a depending lug Zon the endwise movable bar 6 (Figs. 1, 3, and 4), and lateral arms Zeach connected by a pendent rod or link Z with one of a pair offoot-levers or treadles L which are pivotally supported on the machineframe, preferably by a bolt connecting the bars or braces 11 and havingsleeves a thereon which separate the foot-levers from intermediatebraces L The braces or supports L are each pivoted at one end to one ofthe foot" levers L and the other ends thereof are secured onthepivot-bolt carrying the sleeves (A3 And a brace-rod or bar 1connectssaid pivot-bolt with the cross-bar and evener D thus bracing andsustaining the foot-levers against lateral and endwise movement orthrust. The foot-levers L extend from-a point within convenient reach ofthe feet of the driver sitting on the scat'M to a point slightly abovethe pivot of the levers, being preferably curved upwardly to the pointof connection with the links Z and extending thence in a reverse curveto the pivot-bolt and from the latter point upwardly to a rod nto whichthe upstanding'end of the footlever is pivoted. The opposite end of therod n is connected with a laterally projecting arm 0 of an approximatelyT-shaped head-piece on the upper end of a sleeve 0 in which the spindleof the front steering wheel B is journaled; the said sleeve 0 beingfitted in the tubular bracket-bearing E so that it may'turn therein inunison with the spindle when locked thereto and permit the spindle toturn independently of the sleeve when the spindle is unlocked. To thisend a rear wardly projecting arm P is fixed on the upper end of thespindle and has an arc-shaped end which is notched as at p forengagement with a sliding spring-pressed dog Q which is carried by arearwardly extending arm 0 on the head-piece of the-sleeve" O andprovided with a hand-operated connecting rod 9 extending rearwardly to apoint within convenient reach of the driver and having a suitable handleto enable the driver to disconnect the latch or dog from the arm P B,thus causing all three wheels to operate in unison and to be turnedtoward either the m right or the left for steering purposes, by themanipulation of the foo,t-levers L one of which is depressed while theother rises in turning the machine to the right or left. As 'shown, thetongue F is constructed in two parts 1', and r secured together bymetallic straps r and bolts passing through holes in said straps andthrough registering holes in the tongue. The adjoining ends of the twoparts 1', r of the tongue may be recessed so that when brought togethersuch recesses will form a slightly elongated slot or opening 1* toreceive the correspondingly shaped body of the bracket-bearing E,whereby the tongue is permitted to swing sidewise to the same degreethat the wheels turn for steering purposes, and thereby aid in thesteering; the pull of the team causing the tongue to swing to eitherside when turning. The sidewise movement or swingof the tongue islimited so by contact of the rear end thereof with one of the stopsformed by the braces d and vertical movernentyor swing of the tongue islimited by contact of its rear end with one of the stops formed by theupper and lower members of the cross-bar and evener D. This connectionalso permits suflicient longitudinal movement to adapt the tongue toswing sidewise just to the degree that the wheels turn and no farther,and it is free to swing at all times within the limits permitted by itsslotted and ivotal connection with the steering wheel spindle and thestops between which its rear end is confined.

The seat M is mounted upon or secured to a bar S'Which is bent uponitself and has its ends bolted or otherwise secured to links .9 risingfrom the frame-bars a while the rearwardly projecting and folded portionof the seat-bar forms a slot or guide-way to receive a fastening boltunderneath the seat which may be slid along said bar for securing theseat at an desired point, to accommodate drivers 0 different weights; asuitable washer or plate and fastening device or nut being secured onthe free end of said fastening bolt underneath the seat-bar.

The trolley-frames I, I, which carry the bails H, H, also carr yokes H Hhaving pendant arms each tted in an eye or slot "in a plate It carriedby the adjacent rig or gang C, whereby the rigs at opposite sides of themachine may be shifted bodily laterally, for wider or narrower spacing,or for varying the width between rows. As will be seen, the slottedplates accommodate the vertical movements of the cultivator beams andalso hold them to the trolley frames, and as the trolley frames aremoved laterally the cultivator gangs will also be shifted laterallybodily, so that by shifting the trolley frames the gangs of cultivatorsmay ,be readily adjusted to the spacing of the rows. Rollers i on thetrolley frame and suitably journaled therein rest upon the rearcross-ibar a, to reduce friction, and said frame may be formed orprovided with a rearwardly projecting ratchet or rack 6 preferably anintegral part thereof, for engagement with a pawl or sliding dog on therig-shifting lever T. The axles of the rollers i are conveniently journaled in the trolley frame-bars i and i", which are arranged one oneach side of the crossbar a, so as tohold the trolley-frame in positionon said bar when moving toward either side, and extend downwardly to thebail H, which is secured thereto to adapt it to move laterally with thetrolley-frame. Levers T each have a pivotal connection at one end withone of the frame bars, as at t, and a pivotal connection, as at 25 withthe sliding trolley frame, so that the latter may be moved toward eitherthe right or the left, for shifting the rigs laterally, by operatingsaid lever T. After making the desired adjustment the lever may belocked by means of the springpressed dog thereon engaging the rack i onthe sliding trolley frame.

A rock-shaft V journaled on the trolley frame has a crank-arm at one endrigid. therewith and at the other end a crank-arm sleeved thereon, andfrom each of said crank-arms is suspended a rod '2; the lower end ofwhich is pivotally secured to one of the rigs C. A master-lever W, looseon the rock-shaft, is adapted to be locked in any desired position, by apawl or sliding dog thereon engaging a rack w on the rockshaft. Besidethe rack in are placed two levers X, and X each provided with a pawl orsliding dog engaging a rack beside the lever W, so that the levers X andX may be locked to the lever W to cause the three levers to movetogether, at the same time rocking the shaft in its bearings andsimultaneously raising or lowering the two rigs, according to thedirection in which the master-lever is turned. The lever X fast on therock-shaft so as to turn therewith for independent adjustment of the rigwith which the fixed-arm of the shaft is connect .e'd, while the leverX. is secured to the crank-arm which is loose on the shaft in order toprovide for independent adjustment of the rig with which said loosecrankarm is connected, and so long as the two levers and X are locked tothe lever W the three levers will move together, simultaneously raisingor lowering both rigs,but either lever X or X may be unlocked andprovided y the master lever operating simultaneously on both rigs. Acoiled spring 3 may be fitted on each of the rods '11, be tween ashoulder thereon and the rig, so-as to hold the latter,yieldingly downto its work.

As stated, the transverse frame-bar D serves also as an evenerordraft-bar, and to this end a sheave or pulley 1 is journaled betweenthe upper and lower members of .said frame-bar, at or near each end, anda flexible connection, such as a rod 2 and chains 3, at the ends of therod, may extend around the pulleys for connection with a double-tree orother draft device at each end of said flexible connection.

It will be observed that the foot-levers are used for steering andguiding purposes, through their connections with the three steering andsupporting wheels, which may be thus operated quickly and in unison, fordodging purposes. It may be desirable, at times, to steer all threewheels by the foot-pedalsand at the same time shift the rigs in oneoperation, and to this end holes t are rovided in the connecting bar 6registering with holes in the levers T, T, so that by removing thepivot-bolts t, t, and inserting them in the holes t the operator maysteer all three wheels and at the same time'shift the rigs laterally bymanipulating the foot-pedals.

In order to avoid the necessity of a man riding on the machine 'to guidethe wheels through the foot-pedals when the machine is being transportedfrom field to field, or place'to place, a strap Z may be provided havingone end pivoted to the connecting bar band a hole in its free endadapted to be sprung over the end of the ivot -bolt t, of therig-shifting lever T, and t ereby hold the steering and guidingmechanism in a fixed osition with all three wheels moving straig tahead.

The operation of the invention will be readily understood from theforegoing description, when taken iii-connection with the accompanyingdrawings, and further explanation is therefore deemed unnecessary.

t will be readily noted, and especially upon 7 referring to Figs. 1, 2and 3, that Iehave provided a very compact and strong machine which maybe turned in a small space and which will respond quickly to the move-'ment of the steering mechanism so that very little labor is required ofthe operator. By locating the wheel B in front of and between theside-wheels, the said front wheel serves as a tongue support, and alsofacilitates .themaking of a very short turn to either 'side when free tocaster. The bar D forms a rigid part of the main frame so as supportsthe ,draft devices so as to bring the applicationof the draft as near aspossible to the cultivating devices. The number of arts of the machineis consequently reduc and brought into a very compact form, and as thedraft devices are arranged in rear of the front steering wheel it willfollowinstantly themovement of the draft animals from side to side, soas to effect the desired short turning. As shown, the foot levers foractuating the steering mechanism are pendantf levers so hung on the mainframe as to extend under the arched axle in the position in which theymay be most conveniently reached by the driver and most comfortably andeasily operated by him. This arrangement also aids in producing a verycompact machine and in increasing its efficiency.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:
